Mounting The Sensor; Long-Term Deployment In Wet Conditions - Camtraptions PIR V3 Manual

Mounting the Sensor
There is a standard tripod socket on the bottom of the sensor that allows it to
be mounted on a tripod or similar mounting accessory.
The device also has attachment points for a strap on either side so that it can
be strapped to a post or tree trunk.
The sensor is sealed so that the electronics and batteries are protected from
precipitation. However, it is possible for water to trickle inside via the camera
connecting cable socket if the sensor is not mounted with this socket facing
downwards. Therefore, it is important to mount the sensor the correct way up.
Long-term Deployment in Wet Conditions
The Camtraptions PIR v3 is weather-sealed but it is still possible for moisture
to enter the device, particularly via the connecting cable socket. For long-term
deployment in wet and humid conditions, it can be a good idea to use
bathroom silicone sealant on this socket to improve the seal. Make sure the
bung or camera connecting cable are inserted into the socket and then apply
the sealant around the insert. Do not apply sealant if the bung or cable are not
inserted as it may get into the cable socket and make it unusable for wired
connections. As an additional precaution, you may also want to insert a small
sachet of silica gel desiccant inside the PIR (behind the batteries).
